Tough Marines there in that Heat.
I went on a detachment out there in late July 1978, and when the door to the C130 we flew out on opened up, it was as if someone had turned on a giant hair dryer and was pointing it right up the ramp.
My best friend (buddy system) who got sent to California, came out on his motorcycle to visit me while I was out there, and it was so hot, all we did was stay in his motel room, drink, and just catch up with what was going on.
At one point, I wanted to run across the street to a Taco Bell (IIRC) so I opened the door, ran out into the road, got about a quarter way across, and my bare feet felt like they had burst into flames! Talk about stupid, I didn’t even think about it, but I can tell you, I ran back to my room and put my feet in the bathtub!
It sure does get hot out there in July!
